加解密xml，获取根节点处理接口数据

接口加解密，获取根节点处理xml

定义xml，后台模拟post请求

public static void main(String[] args) {
		String parameters1="<?xml version=\"1.0\" encoding=\"utf-8\"?>" +
				"<CS_PROJECT>" +
				"<PROJECT_CODE>1</PROJECT_CODE>" +
				"<PROJECT_NAME>2</PROJECT_NAME>" +
				"<ZT>1</ZT>" +
				"</CS_PROJECT>";		
		try {
			String encodeBase64String = Base64.encodeBase64String(parameters1.getBytes("UTF-8"));//转utf-8
			byte[] encodeBase64String1 = Base64.decodeBase64(encodeBase64String);
			String str2=new String(encodeBase64String1);			
			System.out.println("打印："+str2);			
			Map<String, String> parameters = new HashMap<String, String>();  
	        parameters.put("XMLCONTENT", encodeBase64String);  
	        parameters.put("DATA_SET_CODE", "MzgzNjA2NDc1NjMzODM0Mw");//其它和xml一起传递的参数 
	    	System.out.println(parameters);
	    	String sendPost = sendPost("http://127.0.0.1:8080/project_cs/receives/receivejk",parameters);
		} catch (UnsupportedEncodingException e) {
			e.printStackTrace();
		}
	}

后台模拟post请求

 public static String sendPost(String url, Map<String, String> parameters) {  
        String result = "";// 返回的结果  
        BufferedReader in = null;// 读取响应输入流  
        PrintWriter out = null;  
        StringBuffer sb = new StringBuffer();// 处理请求参数  
        String params = "";// 编码之后的参数  
        try {  
            // 编码请求参数  
        	 if (parameters.size() == 1) {  
                 for (String name : parameters.keySet()) {  
                     sb.append(name).append("=").append(parameters.get(name));  
                 }  
                 params = sb.toString();  
             } else {  
                 for (String name : parameters.keySet()) {  
                     sb.append(name).append("=").append(parameters.get(name)).append("&");
                 }  
                 String temp_params = sb.toString();  
                 params = temp_params.substring(0, temp_params.length() - 1);  
             }  
            // 创建URL对象  
            java.net.URL connURL = new java.net.URL(url);  
            // 打开URL连接  
            java.net.HttpURLConnection httpConn = (java.net.HttpURLConnection) connURL  
                    .openConnection();  
            // 设置通用属性  
            httpConn.setRequestProperty("Accept", "*/*");  
            httpConn.setRequestProperty("Connection", "Keep-Alive");  
            httpConn.setRequestProperty("User-Agent",  
                    "Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1)");  
            // 设置POST方式  
            httpConn.setDoInput(true);  
            httpConn.setDoOutput(true);  
            // 获取HttpURLConnection对象对应的输出流  
            out = new PrintWriter(httpConn.getOutputStream());  
            // 发送请求参数  
            out.write(params);  
            // flush输出流的缓冲  
            out.flush();  
            // 定义BufferedReader输入流来读取URL的响应，设置编码方式  
            in = new BufferedReader(new InputStreamReader(httpConn  
                    .getInputStream(), "UTF-8"));  
            String line;  
            // 读取返回的内容  
            while ((line = in.readLine()) != null) {  
                result += line;  
            }  
        } catch (Exception e) {  
            e.printStackTrace();  
        } finally {  
            try {  
                if (out != null) {  
                    out.close();  
                }  
                if (in != null) {  
                    in.close();  
                }  
            } catch (IOException ex) {  
                ex.printStackTrace();  
            }  
        }  
        return result;  
    }  

接口接收传递信息，并返回接收结果

public JSONObject  receivejk(HttpServletRequest request,@RequestBody String params) {
		JSONObject json =new JSONObject();//是否接收到返回信息
		String XMLCONTENT=request.getParameter("XMLCONTENT");
		String replaceAll = XMLCONTENT.replaceAll(" ","+");
		String sparams=replaceAll;
		byte[] encodeBase64String1 = Base64.decodeBase64(sparams);
		try {
			String str2=new String(encodeBase64String1,"UTF-8");
			//System.out.println("打印："+str2);
			Document dom = DocumentHelper.parseText(str2);
			Element root=dom.getRootElement();
			String text = root.element("ORGANIZE_FORM").getText();
			String text2 = root.element("PURCHASE_MODE").getText();
			/*
			*在此处判断并处理业务
			*/
		json.put("MESSAGE", true);// 规定状态信息的字段名称，默认：msg
		} catch (Exception e) {
			e.printStackTrace();
		}	
		return json;
}
